FIRE-ESCAPE.

Specification of Letters Patent.

Patented Jan. 27, 1914.

Application filed February 29, 1912. Serial No. 680,767.

To all whom it may concern:

Be it known that I, NORMAN MnoLnon, a subject of the King of Great Britain, residing at Smiths Falls, in the county of Lanark, in the Province of Ontario, Dominion of Canada, have invented certain new and use ful Improvements in Fire-Escapes; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to improvements in fire escapes, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel construction and arrangement of parts, whereby the use of pulleys and their accompanying friction or clamping devices on the guy rope is obviated by reason of the particular formation of the clamp and whereby the head and upper portion of the body of the individual descending is protected by the novel formation of the receptacle.

The objects of the invention are to devise a portable form of fire escape which can be conveniently carried by any traveler, to improve the efliciency and safety of such devices, and generally to provide a simple, cheap and durable form of life saving apparatus for fires.

In the drawings, Figure 1 is a perspective view of a window, showing the device attached thereto with the ropes broken away. Fig. 2 is a perspective view of the clamp, which is to be attached to a window sill and over which the rope is to run. Fig. 3 is a side elevation of the clamp, showing the rope and a portion of the window sill and wall broken away.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is a window having the brackets 2 securely attached to the sill 3 thereof, by means of the hooks 4:.

5 is a spindle secured between the brackets 2.

6 is a sleeve, loosely mounted on said spindle 5, having at one end thereof the notches 7.

S is a dog pivotally secured on the inner side of one of the brackets 2 and engaging with the notches 7.

9 is a rope wound around the sleeve 6, one of said ropes being secured to the receptacle 10 by means of the cord 11, while the other end hangs free and serves to regulate the speed of the descent. It will be readily understood, that dog 8 will prevent the sleeve 6 from turning in that direction and provide a solid spindle. The intention is to procure means to facilitate the pulling up of the receptacle 11.

12 are extension arms having the longitudinal slots 13 intermediate of their length and the roller 14 secured in suitable bearings at one end, said arms being secured to the brackets 2 by thumb screws 15. In this manner the brackets can be adjusted to the size of the sill and the rope 9 adapted to roll over said roller 14.

The receptacle 10 is formed with a flap 16 which normally hangs down inside, against the back of the receptacle. Should it be necessary, however, to pass a window or like place out of which tongues of flame are shooting, this flap may be snapped to the cords 11 and thus protect one from the flames. Both receptacle and flap are preferably made of some fireproof material.

The cord 11 passes through the hole 17 in the stave 18 and then extends down the side of the receptacle, through a hole 19 in the base board 20 which forms the bottom of the receptacle, along the under part of this base board, and up through the other side. This keeps the sides of the receptacle stable in an upright position when in use. The stave 18 is adapted to keep the mouth of the bag in its open position.

21 are fasteners for securing the fire proof covering to the base board.

In the operation of this invention, when a fire breaks out the brackets 2 are attached to the window sill by means of the hooks at as illustrated, the rope 9 having been first wound around the intermediate part 5 of the said brackets. The person or persons desiring to descend then step into the receptacle and the free portion of the rope is grasped by the hand and allowed to pass through slowly, thus regulating the speed of the descent to the ground. The receptacle can be returned for more passengers as often as desired, simply by pulling on the free end of the rope, which proceeding naturally elevates the said receptacle.

That I claim as my invention is:

In a fire escape, a pair of grappling hooks and a spindle therebetween connecting said hooks, said hooks being adapted to grip a window sill, a sleeve loosely mounted on said spindle having notches in one end, a pawl engaging in said notches, being adapted to hold said sleeve against rotation in one di- Signed at the town of Smiths Falls, Onrection, a pair of extension arms adjustably tario, Canada, this thirteenth day of Febmounted on said hooks, aroller journaled in ruary A.
